Phenolic compounds arise from the shikimic and acetic acid (polyketide) metabolic pathways in plants. They are but one category of the many secondary metabolites implicated in plant allelopathy. Phenolic allelochemicals have been observed in both natural and managed ecosystems, where they cause a number of ecological and economic problems, such as declines in crop yield due to soil sickness, regeneration failure of natural forests, and replanting problems in orchards. Phenolic allelochemical structures and modes of action are diverse and may offer potential lead compounds for the development of future herbicides or pesticides. This article reviews allelopathic effects, analysis methods, and allelopathic mechanisms underlying the activity of plant phenolic compounds. Additionally, the currently debated topic in plant allelopathy of whether catechin and 8-hydroxyquinoline play an important role in Centaurea maculata and Centaurea diffusa invasion success is discussed. Overall, the main purpose of this review is to highlight the allelopacthic potential of phenolic compounds to provide us with methods to solve various ecology problems, especially in regard to the sustainable development of agriculture, forestry, nature resources and environment conservation.
酚类化合物来源于植物的莽草酸和乙酸（聚酮）代谢途径。它们只是参与植物化感作用的众多次生代谢物中的一类。在自然和管理生态系统中都观察到了酚类化感化合物，它们会引起许多生态和经济问题，例如由于土壤疾病导致的作物产量下降、天然林再生失败以及果园重新种植问题。酚类化感化合物的结构和作用方式多种多样，可能为未来除草剂或杀虫剂的开发提供潜在的先导化合物。本文综述了植物酚类化合物的化感作用、分析方法和作用机制。此外，还讨论了关于藜麦和曼陀罗入侵成功中儿茶素和 8-羟基喹啉是否起重要作用的植物化感作用中目前有争议的话题。总的来说，本文综述的主要目的是强调酚类化合物的化感潜力，为我们提供解决各种生态问题的方法，特别是在农业、林业、自然资源和环境保护的可持续发展方面。
